Dr. Aaraveeti Ramayogaiah, a government doctor in the Indian state of Andhra Pradesh, has written 27 thousand postcards about preventive medicine during his career.

High-tech hospitals are now commonplace in Indian cities. But they’re also expensive, putting them out of the reach of the poor.

So one Indian doctor found an ultra low-tech approach to delivering health care: writing postcards.

Over the course of his career, Dr. Aaraveeti Ramayogaiah wrote about 27,000 postcards to patients and acquaintances. Most of them explained preventive health care practices, like washing hands and boiling water. The postcards were intended to help thousands of people who couldn’t afford or easily get to a physician.

“He started seeing how health in India was driven by the profits , which was largely linked to the pharmaceutical industry,” says Rahul.

The high costs of care inspired Ramayogaiah to take a different approach. He collected the postal addresses of thousands of patients and even strangers. In his postcards, he explained that some health issues — like diarrheal diseases — can be avoided without medical treatment.

He argued that in communities where doctors are difficult to access, residents should focus on improving sanitation and the environment.

His postcard campaign and editorials made headlines in Indian newspapers. But he told Rahul that some outlets didn’t take him seriously, because of his rigid stance against high-priced corporate hospitals.

Recently, Ramayogaiah’s opposition to expensive health care became deeply personal. “He’s suffering from cancer right now,” says Rahul. A brain tumor has left him bedridden and weak.

Yet even in his poor health, Ramayogaiah remains skeptical of India’s for-profit hospitals. “He doesn’t want to go to a good hospital to treat himself,” says Rahul.

“He has fought his whole life against the system of corporatization of health,” Rahul adds. “Which is the only system that can help him extend his life a little longer. In some sense, for him, his principles were more important than life itself.”
